best manual Tiptronic mode: just tap the shift lever left or right
at any time. You never have to move the shifter into a dedicated
"manual" slot. It's always ready for manual control. That's

like BMW and Porsche do with their requiring you to jam the shift lever
all over the place just to drop down a gear to go down a hill.
